Product Description

What this part is:

RHP 7018CTBSULP6 is a single universally ground angular contact ball bearing, ISO series 10 (70xx), with a 90 mm bore, 140 mm outside diameter and 24 mm width. Contact angle 15°, light preload (L), precision class P6 (ISO Class 6, ABEC 3, RHP class code EP3). Supplied as 1 Pc.

Decoding the designation:

7018 — ISO dimension series 10, bore code 18, giving 90 x 140 x 24 mm.

C — 15° contact angle.

TB — one-piece machined laminated phenolic cage, inner-ring centred.

SU — single universally ground, so two or more identical bearings stack back-to-back, face-to-face or in tandem without shims or spacers.

L — light preload.

P6 — ISO Class 6, ABEC 3, RHP class code EP3.

B7018X2TULEP3 — the RHP B-series form on the same carton; X2 is a 15° contact angle and EP3 is P6.
